  54ch10 serves pre-interact risk briefs for wallet addresses, tokens and URLs — phishing, scam,
  honeypot and URL-reputation heuristics an agent can call BEFORE it signs, approves, bridges or
  opens a dapp URL. A brief returns a 0–100 score where higher is more concerning, a band, flags,
  a summary and the sources behind it, so a caller can gate its next tool call on policy: refuse
  on critical, require human confirmation on elevated. The provider describes it as analytics-only
  and explicitly not financial, legal or investment advice. Four operations over OpenAPI 3.0,
  bearer authenticated, with a free tier and an x402 machine-payment surface on Base.

    Submitted via apis.io/add on 2026-08-24 and auto-published by the gate at rating 37. The
    submitted APIs.json at https://54ch10.uk/apis.json returns 404 against a control that also
    404s with an identical 531-byte JSON body, so the 404 is real — a bad pointer in the
    submission, not an absent surface. There is no llms.txt either.
    What IS served was fetched and confirmed: OpenAPI 3.0.3 at /openapi.json (4 paths, bearer
    auth, though zero component schemas), an AGENT.md written directly at agents rather than at
    humans, and an x402 discovery document at /.well-known/x402 declaring x402Version 2 on the
    Base network with the payai facilitator. /health returns 200 JSON. Both brief endpoints return
    400 JSON on a malformed call, which is validation rather than a stub.
    The AGENT.md is the interesting artifact: it tells a calling agent the order of operations —
    resolve the target, GET /v1/brief, then gate the next tool call on the returned band — and
    tells operators to log cached_at and sources[].status so they can tell a stub signal from a
    live one. It is kept here in full.
    Note the brand: the provider states it is "54ch10", NOT "SACHIO".
